Caption: Satellite image of tropical cyclone Debbie off the northeast coast of Australia. The cyclone, which has a 100 kilometre core, is due to make landfall in Queensland on the morning (local time) of Tuesday 28 March. At the time this image was taken the cyclone was a category 4 storm, with winds up to 251 kilometres per hour, but could intensify before landfall. Around 25,000 residents have been evacuated from low-lying areas that are at risk of flooding as the storm is likely to coincide with a high tide.
